KNOW ALL 'MEN BY THESE PRESENTS:

That I, ISAAC D. MATHEWS, of the city and county Aof Worcester, andCommonwealth of Massachusetts, have invented certain new and usefulImprovements in .Iournal-Boxesgxand I do hereby declare that thefollowingis -a full, clear, .and exact description of the sanne,`reference being had to the accompanying drawings, forming a. part ofthis specification, in which` Figure, 1 represents n perspective view ofone-cf my improved journal-boxes, as it appears when applied to use; andv Figure '2 represents a vertical central section of the box and shaft.

To enable those skilled in the art to which myinvention belongs to malteand use the same, I will proceed to describe it more in detail. l Y i Inthe drawings, A is the hanger, having' two projections, Bl and C, inwhich are the adjustingbolts D E, which help to support and retain theouter shell F of the journal-box G in place. Within the shell F is aninner box, I, the lower half, J, of which has a rounded projection, a,which rests and turns in a concavity, 6, in the bottom, K, ofthe shellF. The latter has a. projection, c, which enters a recess, eZ, in thepart a. The upper half, L, of the inner box I is retained in properposition by the cap M, which ts over the rounded projection, e, of thepart L. Two oil-holes, ff, are made in the part L, while the two pointedprojections, gg, upon the undersides of the two end caps, F F', of theshell F, point directly into the tops of the oil-holes ff. The shaft Nmay be turned down to receive the inner box I, as shown in the drawings,if preferred. Bevelled collars, O O, are placed upon'the shaftwithin theshell F, asshown in the drawings.` Wires or pieces of metal, l 1or othersuitable material, are fastened to the collars O O, so' as to projectinto the space between the box I and shell F, as indicated in thedrawings. y

v The operation is as follows: A quantityof o'il or lubricatingsubstance isturned into the shell F, which runs into the bottom oftheShell F, from which it is brought up by the ends ofthe wires l 1, and asthese wires strike against the points g g, the oil or lubricatingsubstance is scraped off, and drops from 4the points g g into thev holesand passes down to lubricate the bearing partslof the shaft and box. Thecollars O O prevent the oil'from running outupon ythe shaft beyond theshell F. The-collars O O may be made with a shell to extend up over theends ofthe box I, to take up and throw the oil upon the points g g, ordrop it into the holes ff. The edges of the collars O O, when thusextended, may have bristles or some fibrous substance or small yieldingwire points attached thereto to deliver the oil to the pinsg g. Thewires 1 1 are made so as to draw against the points g g, whereby the'oilis scraped off. This is effected by inclining their ends2 2, back ofthe` pointsof their. attachment to the collars O O. i

It will be seen that the box I can turn `i'reely to conform tothepositions ofthe shaft as it revolves, wherebyl all binding of the partsis obviated. The shell part F is bolted tothe hanger A, the bolt beingpassed through a slot in the hanger, lso that the s'hell can be set upor down. The shell may be applied to a stationary bo-x or bearing withgoed results, the shaft being provided with the collars andoiling-npparatus, substantially as above described. The invention isequally applicable to shafts which have no bearings turned down, asshown in the drawings.. m m are caps, which cover the oil-holes it n, toprevent the entrance of dust and dirt.

Having described my improved journal-box or bearing, what I claimtherein as new and of my invention, and desire to sceureby LettersPatent, is-

1. The combination, with the inner box I, of the shell F,substantiallyas and for the purposes set forth.

2.. The combination, with the shell F and the points'or projections g g,ofthe collars O-O and oilers 1 I, substantially as and for the purposesset forth.

S, The combination, with the bearing or journal-box of ashaft, of one ormore collars O and Oilers' 1, substantially as and for the purposessetforth.

4. The combination of the points g g with the caps F4 F and the toppart, L, of thebox I, substantially as and'for the purposes sot forth. l

5. The combination of the Oilers 1 l with the'collars 4O O, asdescribed, whereby they draw against the points or projections g y,which scrape thev oil from the oilers, as set forth.

6. The combination of the shell F ande-aps F F with the collars O O andoilers 1 l and shaft N, substantially as and for the purposes set forth.ISAACV D. MATHEWS.
